MACHINE FOR TREATING SHINGLES.

SPECIFICATION forming part of Letters Patent No. 406,045, dated. July 2, 1889.

Application filed N ovembcr 1, 1888.

To all whom it may concern.-

Be it known that I, lVILLIAM ll. HEATH, of Taunton, county of Bristol, State of Massachusetts, have invented an Improvement in Machines for Treating Shingles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide a machine for smoothing or finishing shingles such as commonly employed in the construction of houses.

In accordance with my invention the shingle is subjected to the cutting action of a knife or knives on one or both its sides, ac cording to the kind of shingle treatedthat is, whether the same has been split or sawed from the log-the said knife or knives being moved from the butt to the tip of the shingle in converging guides to conform to the tapering form of the shingle.

Another feature of my invention consists in mechanism by which the movement of the knife is automatically stopped after it has acted upon the shingle, as will be hereinafter described.

My invention therefore consists, essentially, in the combination, with a knife to trim the surface of the shingle, of a guide and a carrier for said knife, a main shaft, a counter-shaft provided with a clutch driven from the main shaft and adapted to rotate the counter-shaft, and a shipper mechanism connected to said clutch to move the said knife over the surface of the shingle on the rotation of the said shaft, substantially as will be described.

Other features of my invention will be pointed out in the claims at the end of this specification.

Figure 1 is a side elevation of one form of machine embodying my invention; Fig. 2, a longitudinal section, partially broken out, of a sufficient portion of a machine to enable it to be understood, the section being taken on line a; 00, Fig. 3; Fig. 3, a top or plan view of the machine shown in Fig. 1; Fig. i, a rear end elevation of the machine shown in Fig. 3; Fig. 5, a section of a modification to be referred to, the section being taken on line y y, Fig. 6; and Fig. 6 a top or plan view of part Serial No. 289,770. (No model.)

of the mechanism shown in Fig. 5; Fig. 7, a detail to be referred to; Fig. 8, a detail in elevation of the jaws; and Fig. 9, a sectional detail to more clearly show the guides for the knives.

The frame A, of sufficient strength to sustain the working parts, supports in suitable boxes a, secured, as shown, to the rear side of the frame, a main shaft a, provided with the usual driving-pulley a The main shaft to has mounted upon it a pinion a, which meshes with and drives a gear-Wheel a on a shaft a", supported in suitable bearings a, (see Fig. 4,) the said gear-wheel constituting part of a clutch mechanism, to be described.

The gear-wheel (0* is provided, as herein shown, with an elongated hub a having at one side of the said gear anannular groove (0, which is engaged by forked arms a of a rod a (see Fig. 2,) herein shown as secured to a bar a, pivoted to the frame A by a threaded bolt a, the said bar forming a part of the shipper mechanism, it being connected, as herein shown, by rod a to bar a, pivoted, as at a (see Fig. 3,) to a bracket a secured to a cross-bar a of the frame A, the bar a being connected bya link or bar a (see Figs. and t) to the shipper-lever a, pivoted to the frame, as at (U The hub (0 on the other side of the gearwheel a is provided with a shoulder a (see Fig. 4,) to engage a shoulder ta on a hub or collar a, fast on the shaft (1, the said shaft being rotated when the shoul- (l616t on the hub engages the shoulder at on the hub (L27 in the rotation of the gear-wheel.

The shaft (0 has mounted upon it, as herein shown, within the sides of the frame A at its opposite ends, two disks 1) Z), provided with crank-pins b D, to which are connected one end of links I)" 12"", secured at their opposite ends to levers b b, pivoted to the frame of the machine, as at Z)", the said levers constituting carriers for one or more knives b having their ends inserted through slots U in the said levers and bent to form arms N", which are fitted into guideways I) Z), (see Fig. 2,) secured to the sides of the frame.

The guideways o I) are made inclined from the rear toward the front end of the machine, so that as the knives are moved forward, through their carriers and links con nected to the disks on the shaft a, the said knives will gradually converge or approach each other, and thus conform to the tapering form of the shingle, whereby the latter, with the machine shown in Fig. 2, is smoothed or finished on both faces at the same time.

In operation, when both sides of the shingle I) are to be smoothed or finished, as will be the case with a split shingle, the said shingle is insert-ed between the knives b and has its rear end or butt gripped between jaws c c, the jaw a being herein shown as rigidly secured to the frame, (see Fig. 2,) and the jaw 0' pivoted, as at 0 and connected at its rear end by rod 0 to a foot treadle or lever 0 pivoted or suspended, as at c, said treadle having its front end extended through a slot 0 in a bracket 0 (see Fig. 1,) secured to the frame A, and provided with a notch to form a lock for said lever, the said treadle having connected to it, as shown, one end of an elevating-spring c", by which the lever 0 when disconnected from a notch in the bracket 0 is raised to unclamp the lower jaw 0', when it is desired to remove a shingle from between the jaws-that is, after the said shingle has been finished-the treadle 0 being engaged with the notch, as shown in Fig. 1, when the shingle has been placed in position to be operated upon.

The front or tip end of the shingle will be supported in suitable manner-as, for instance, in a notch d in a bar (1, secured to the frame A.

In order that the knives may be automatically stopped when brought to their normal or starting position, as shown in Fig. 2, after having finished a shingle, the shipping mechanism is automatically operated to disengage the clutch portion of the hub a from its eooperating portion a, fast on the shaft a. To accomplish this result, the disk I) is provided, as herein shown, on its periphery with a stud or pin e, (see Fig. 3,) which acts upon the end of a locking-bar 8, (see Figs. 1, 4, and 7,) secured, as by bolt 6 to the bar ca of the shipping mechanism, the said bolt, as herein shown in Fig. 4, being extended through a slot in the said bar to permit of vertical movement of the said bar, the bar 6 havingits front end shouldered, as at 6 to engage a notch e in a plate 6 secured to the frame A, (see Fig. 3,) and to lock the shipping mechanism in operative position, the said shoulder being thus engaged with its notch when the shoulder a of the hub a is engaged with the shoulder a of the hubon the shaft.

In order that the movable jaw 0 may be loosened automatically after the shingle has been finished, the bar a is provided, as herein shown, with a projection a (see Fig. 1,) which acts against the lever c and disengages it from its notch in the bracket 0 thereby permitting the spring 0 to elevate the said lever, and through it to disengage the movable jaw.

In some instances it may be desired to stop the machine at any part of the travel of the knives; and for this purpose Ihave provided aleverf, (see Fig. 1,) having one end extended beneath and in line with the projecting end of the bar e, the other end of the lever f hav- I ing secured to it a rod f, herein shown as extended througha suitable guide f (shown as a staple,) and provided above the frame of the machine with a handle f so that by depressing the rod f the lever f maybe turned on its pivot f to bring its free end into engagement with the bar a and raise its shoulder e from thenotch 6 thus permitting the spring 20, secured to the bar a of the shipping mechanism, to disengage the hub a of the gear from the hub on the shaft.

Then the shingleto be treated is what is known as a sawed shingle, one of the knives may be dispensed with, preferably the lower one, and the upper knife employed to act on or trim the upper surface or face of the shingle, the latter in this case being sustained in correct position by a supporting frame or bed, (shown as a board or plate g,) provided with arms g, which rest upon ledges or shoulders 9 (see Fig. 3) on the sides of the frame.

The inner end of the supporting frame or bed is secured between the jaws c c, and the shingle is secured to the said bed, as herein shown, by a stud or pin 9 (see Fig. 6,) having a sharpened point to pierce the shingle.

I claim 1. In a machine for treating shingles, the combination, with aknife, of a guide inclined from one toward the opposite end of the machine and in which the said knife travels, levers on opposite sides of the machine, to which the said knife is secured, and jaws to hold one end of the shingle, a main shaft, a counter-shaft provided with a clutch driven from the main shaft and adapted to rotate the counter-shaft, and a shipper mechanism connected to said clutch, substantially as described.

2. In a machine for finishing shingles, the combination, with knives, of converging guides in which the said knives travel, carriers for said knives, and jaws to hold one end of the shingle, a main shaft, a counter-shaft provided with a clutch driven from the main shaft and adapted to rotate the counter-shaft, a shipping mechanism connected to said clutch, and a stop carried by the counter-shaft to act on the shipping mechanism and auto matically disengage the clutch to stop rotation of the counter-shaft, and thereby travel of the knives, substantially as described.

3. In a machine for finishing shingles, the combination, with knives, of converging guides in which the said knives travel, carriers for said knives, and jaws to hold one end of the shingle, a main shaft, a counter-shaft provided with a clutch driven from the main shaft and adapted to rotate the counter-shaft, and a shipping mechanism connected to said clutch, a locking-bar secured to the shipping mechanism, a lever f to act on said bar to disengage the shipper mechanism to stop the travel of the knives, substantially as described.

4. In a machine for finishing shingles, the combination, with knives, of converging guides therefor and carriers for said knives, a fixed jaw and a movable jaw to hold the shingles, and a lever, as 0 connected to the movable jaw, a lock for said lever, a main shaft, a counter-shaft provided with a clutch driven from the main shaft and adapted to rotate the counter-shaft, a shipping mechanism connected to said clutch, a stop carried by the counter-shaft to act on the shipping WILLIAM H.
